Application filed November 9, 1907. Serial No. 401,505.

To all whom it may concern:

Be it known that I, WILLIAM L. MOORE, a citizen of the United States, residing at Humboldt, in the county of Gibson and State of Tennessee, have invented a new and useful Heater, of which the following is a specification.

This invention relates to heaters of that character utilizing hydrocarbon oil as fuel and the principal object of the invention is to provide a device of this character having means whereby products of combustion are directed successively through a distributing flue and a plurality of return flues, all of said fiues being exposed to the external atmosphere so that a maximum percentage of the heat generated is utilized for elevating the temperature of a room in which the heater may be located.

Another object is to provide novel means for vaporizing the fuel prior to its discharge at the point of ignition, the products of combustion being utilized for vaporizing fuel.

Another object is to provlde simple and efficient, means whereby the fuel may be initially vaporized as when the heater is being started.

Another object is to provide means whereby the required quantity of air for supporting complete combustion may be drawn into the heater by the force of the fuel directed thereinto.

With theseij 'and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a side elevation of a heater embodying the present improvements. Fig. 2 is a plan view thereof. Fig. 3 is a vertical section therethrough on line 9c-r, Fig. 2. Fig. 4 is a horizontal section through the upper head of the heater and on line y-y, Fig. 3..

Referring to the figures by characters of reference, 1 designates the lower head or drum of the heater, the same being preferably in the form of a cylinder mounted on suitable supports such as legs 2 and this drum is provided in its upper face with a central circular opening 3 in which is secured one end of a central or distributing I flue 4. This flue extends upward through a central circular opening 5 formed in the bottom of the upper head or drum 6 of the heater. The upper end of flue 4 projects into this head 6 for the purpose hereinafter set forth. Formed within the adjoining faces of the two heads and with their centers in circles concentric with the flue 4 are circular openings 7, the o enings in the head 6 being disposed direct y above the corresponding openings in the head 1 and a plurality of return flues 8 are disposed between the two heads with their end portions secured in the openings 7. These return flues are of considerably less area than the distributing flue 4 and in practice the flue 4 will be of substantially the same transverse area as the combined transverse areas of the flues 8.

A circular partition 9 is secured within the head 6 and around the inwardly projecting end of flue 4 so as to form a central circular compartment 10 and an outer concentric compartment 11. Partition 9 is spaced from the end of flue 4 a sufiicient distance to form a channel or trough 12. An outlet opening 13 is formed in the u per face of head 6 near the periphery .thereo' and constitutes an outlet for roducts of combustion. A port 14 is forms within partition 9 close to the outlet 13 and is normally closed by means of a slidable damper 15 mounted in suitable guides 16 and having a stem 17 extending upward from it and beyond the head 6 so that the damper can be readily manipulated.

The upper face of head 6 is preferably formed with a large circular o ening 17 nor mally closed by means of a p ate 18. This plate has a central opening 19 surrounded by a funnel 20 which is secured to and extends upward from the plate 18. A feed pipe 21 extends downward from a suitable tank, not shown, and through the plate 18 below which it merges into a coil 22 which terminates in an upwardly extending gooseneck 23 which projects through the plate 18 and opens downward into the funnel 20. Pipe 21 is provided with a suitable valve 24 whereby the supply of fuel to the coil may be controlled. A branch pipe 25 extends from the feed pipe 21 and through plate 18 and the lower end of this branch pipe is curved laterally as indicated at 26 so as to discharge fuel into the circular trough 12. A valve 27 of suitable form is located in the pipe 25 so that the flow of fuel to the trough can be conveniently controlled.

It is of course to be understood that the two valves 27 and 24 are normally closed. hen it is desired to use the heater valve 27 is opened so that fuel will be free to flow through pipe 25 into the trough 12. After the trough has been filled the flow of fuel is cut oil and that portion thereof within the trough is ignited by inserting a torch through the opening 19. The products of combustion will quickly heat the coil 22 and by opening the valve 24 fuel will be free to pass through the coil where it will be vaporized and will pass upward and outward through the gooseneck 23. The vapor can then be ignited at its point of discharge and the flame will be directed downward through coil 22 and into the distributing flue 4. The force of the flame will be suflicient to draw downward into the heater enough air to completely support combustion. Products of combustion will pass downward through the flue 4 and will be distributed within head 1 so as to pass upward and outward through the return lines 8, head 6, and outlet 13. As all of the flues are exposed to the external atmosphere it will be apparent that the large heating area presented by the various lines will be suflicient to quickly raise the temperature of the air within a room. It will be seen that all of the products of combustion are fed upward through the outlet 13 and a suitable pi e, not shown, may be connected to this out et for the purpose of conducting the spent products to a chimney. The heat generated by the combustion of the vapor is of course sufficient to keep the coil 22 heated to such an extent that the oil supplied thereto will be promptly vaporized.

Importance is attached to the fact that the heat is directed downward through a central distributing flue which is completely surrounded by the outer air and also to the fact that the hot gases are compelled to return through the fines 8 before passing from the heater. Practically all of the generated heat is thus utilized for heating pur oses. It is of course to be understood that if desired the heat can be regulated by partly or entirely opening the valve 24. In starting the stove damper 15 is opened so that smoke can pass directly from the funnel 20 through door 14 to outlet 13. It will be noted that the plate 18 can be readily removed and will carry therewith the coil 22 and the other pipe connections. It is thus possible to thoroughly clean these parts.
